When I parse a file containing escape characters (& or <) in the first tag, CXML:parse-file gives the error message: "Error: Document not well-formed: entity not defined: amp".

Including the characters in other tags works fine. Is this the expected behavior? Example:

Case 1 (escape character in first tag): REPL> (with-open-file (s "example.xml" :direction :output :if-exists :supersede) (write-string "<test a='b&amp;'><child/></test>" s))

--> "<test a='b&amp;'><child/></test>"

REPL> (cxml:parse-file "example.xml" (cxml-xmls:make-xmls-builder))

--> Error: Document not well-formed: entity not defined: amp Context: Line 1, column 16 in file://+

Case 2 (escape character in second tag): REPL> (with-open-file (s "example.xml" :direction :output :if-exists :supersede) (write-string "<test a='b'><child a='b&amp;'/></test>" s))

--> (cxml:parse-file "example.xml" (cxml-xmls:make-xmls-builder)) ("test" (("a" "b")) ("child" (("a" "b&"))))

Edi Weitz suggests that ENSURE-DTD may be called too late in the P/DOCUMENT function.

Thanks for any help.
